目的总结隆突性皮肤纤维肉瘤 (Dermatofibrosarcoma protuberans， DFSP)的超声影像学表现特点，为临床 诊断和治疗提供依据。方法 回顾性分 析11例资料完整并经病理证实的DFSP患 者的超声表现及临床、病理表现。结 果 11例DFSP病例中，累及躯干9例，下 肢1例、右颞部1例。7例为初发病例， 4例为复发病例。病灶大小范围为1.6- 8.3cm(3.8±1.8)cm。超声声像图主要表 现为皮肤及皮下椭圆形、低回声包块，大 多数内部回声不均匀，边界清晰，血流信 号较丰富。所有病例均未发现淋巴结或远 处转移。结论 DFSP的超声声像图具有一 定的特征性，可以为临床提供一定的诊疗 依据。

Objective To analyze the ultrasound imaging features of dermatofibrosarcoma protuberans(DFSP), and to provide evidences for clinical differential diagnosis and management. Methods Clinical data and ultrasound findings of 11 patients confirmed DFSP were analyzed retrospectively. Results Of the 11 patients, 9 were involved the trunk, other locations included low limb (n=1) and right temporal sclap(n=1). Seven were newly diagnosed cases, and 4 were recurrences. On ultrasound imaging, the lesions ranged in size from 1.6-8.3cm (mean, 3.8cm, standard deviations, 1.8 cm). Most of the lesions were nodular and well-circumscribed, with abundant blood supply. None of the patients had evidence of lymph node, or distant metastasis. Conclusion The ultrasound characteristics of DFSP are valuable for clinical differential diagnosis and management.
